Abstract: A closure assembly having two ends comprising a first and second track disposed proximate each end of the assembly respectively, and a slidable and pivotable closure member, the closure member including framing sections thereof and being engaged with the first and second tracks proximate first and second pivots adjacent the pivotable end of the closure member, the first and second pivots being adapted to remain engaged with the first and second tracks while supporting the closure member both when it is pivoted away from the closure assembly and when it is slidable relative to the tracks, each of the first and second pivots including a rotatable pinion disposed therewith for facilitating the movement of the closure member relative to the tracks, wherein the rotatable pinion moves in cooperation with the tracks both when the closure member is pivoted away from the closure assembly and when it is slidable relative to the tracks, said framing sections being formed separately from the tracks, the tracks including an integral rack portion proximate one side thereof, said rack portion including a plurality of teeth extending substantially from end to end of said tracks, and for engagement with the 2729 ו' בתשרי התשס" ג - September 12, 2002 rotatable pinion of said pivot which facilitates the movement of the closure member relative to the tracks, the tracks being fixed in position relative to the framing sections by the provision of first and second supplementary portions, the first supplementary portion being a first block which has two ends, a top and a bottom, the first block having disposed in use proximate the top thereof openings to receive fasteners wherein said openings extend to the bottom of the first block, the fasteners are provided for engagement with the frame portion of the frame and are provided to lock the first block in position in relation to the end of the tracks remote the pivoting end of the closure member, and thereby fixing the tracks in position, the second block having disposed therewith an adjuster (206) moveable in relation to said first block in a direction extending towards said tracks, said adjuster being engageable with the second supplementary portion for engagement with said tracks, the second supplementary portion having elements provided therewith which are engageable with said adjuster and said tracks, said adjuster being moveable in position to move the two supplementary portions in relation to the rack provided with the tracks, wherein movement of said adjuster will move said second portion in relation to said tracks and said rack in a direction toward and away from the first block thereby adjusting the portion of said tracks in relation to said framing sections and thereat fixing said rack in position wherein such an adjustment for the tracks establishes and allows for the alignment or adjustment of the closure member and maintains the parallelism of the pivots in relation to said tracks so that the pivots remain substantially parallel and square to one another. 2730 ו' בתשרי התשס" ג - September 12, 2002
